If sodsirork in orf-lerto provido a self# oonta'inod(lotion, an ordin'ai'y'dry hat-'tr if-9. niay lio arrangedWitlintho' rod in Figs; 3 and 4. In, this 'oase one erm a 10 ot the battery may he in permanent contact with ont` terminal ot the lamp i while thc other terminal 11 ot the battery may he' earthed" to the metal of the device by means ot a spring or plunger 12 interposed between surh terminal and a cap or plug 13 upon the inner end of the rod 3. The said spring 1;) serves also as a means of secur ing the battery 9 in place and lreeplug the terminal l() in contact with thc lamp.

In all eases the arrangement is such that the lan'ip-circuit will be autou'iatieally closed by the. rod 3 when in the outward position. For this purpose an insulated Contact 1.4 is provided upon the rod 3 at the required position and connected with the remaining lamp terminal in each case. by means of an insulated lead 15, while at` t-lie'required posi tion u-pon the ease 1 is arranged also an in sulated terminal 16 with which the said contact 14 adapted to make electrical con nection when the. rod 3 is in the outward position.

The said terminal 1G is eoni'iceted. as by means ot a wire 17, with the remaining terminal ot` the. battery or electrical source S or t) as the ease may be. ln order to avoid an unnecessary waste of current. as would be occasioned by allowing the lamp to light each time the device were used in daylight, a switch 18 is preferably inserted in the lead 17 for the purpose of opening or closing the circuit. as required.

For the purpose of operating the said rod 3 so as to canse it to perform its said telescopic movement, any suitable means may be en'lployed. Thus for example. as shown in Fig. 2. a rack 20 is provided or formed upon the rod 3 and with which rack is adapted to intermesh a pinion 21 rotatably mounted within the case 1. The said pinion is ].irovided with a suitable clock-spring which tends to turn the pinion in such direction as to carry the. rod 3 into the. outward position. while. to restrain the pinion against this tendency of the spring. such pinion is provided with a ratehetswheel 2,2 with which is adapted to engage a pawl or detent 23. By this arrangement. to cause, the signal to he. displayed. the driver releases the pawl 23 from engagement with the ratchet-Wheel. whereupon the pinion being free to rotate under action ot its 'said spring. will carry therod 3 into the outward position. To enableI the. rod to be conveniently restored to its origina-l posit-ion again, a knob or handle 24 is provided upon the said pinion or its spindle and adapted to be, grasped b v the. tinge-rs for the purpose of turning such pinion against the tendency of the spring.

In the form shown in Figs. 3 and 4, the rack and pinion are dispensed with and a spiral spring 25 is interposed between the inner end of the case 1 and the rod. The

By this arrangement, to cause the signal to f be displayed, the handle 2G is simply disengaged from the notch 28. tlms permitting the rod 3 to move spring 25.

It will be obvious however that. thisoperation of the rod 3 may be performedl by varions means such as for instance by the. use of a Bowden-wire or other well-known intermediate devices adapted to be operated by a movement. of the hand. foot; or limbs of the driver. The invention is not'therefore to be limited to any ot' the almveanentioned means ot operating` but includesI within its scope the employment ot' a rod bearing the required sign and adapted to be operated telescopically within a casing by any suitable means.

In practice to enable a signal to be given on either side of the car according to the direction in which the turning is to take place, the construction will be duplicated, that is to say two such devices will be elnployed and arranged one on either side 'of the car.A

1. An indicator of the class described comprising a easing adapted to be mounted upon a suitable. part of a. vehicle. a rod mounted to slide teleseopieally in the said easing` a sign carried bv the rod and adapted to be displayed ltiroin the vehicle when the rod is in its extended. operative position. means tending normally to project, the rod ido operative position, a toothed rack provided o'n the said rod, a pinion journaled in the easing in mesh with the rack, a ratchet carried by the pinion` and a manually operable -releasing pawl engage-d with the said ratchet and adapted normally to secure the rod in inoperative position.

2. An indicator of the class described comprising a. easing adapted to be. mounted upon a suitable part of a vehicle, a rod mounted to slide telesoo'pically in the said easing, a sign carriedby the rod and adapted outward under action of its.

to be, displayed from the vehicle when the mally to project the rod into operative posinames to this specification inthe preence tion, :l ratchet carried by the pinion, and a l of two subscribing witnesses.
